RE: Compiling on OSX LION

I tried both macports and compiling root 5.30.00-patches.

Macport seems not have any answer after more than 2 hours the compiling procedure is still on 
---> Building root  

and for what concerns the compiling fron source after downloading:

svn co http://root.cern.ch/svn/root/branches/v5-30-00-patches root

and 
./configure macosx64 --prefix=/usr/local/root
make   

the error 

/Users/vitopalladino/daq62/root/net/rpdutils/src/rpdconn.cxx: In member function ‘int rpdconn::senddesc(int)’:
/Users/vitopalladino/daq62/root/net/rpdutils/src/rpdconn.cxx:398: error: size of array ‘buf’ is not an integral constant-expression

stops the compiling process.

Thanks for any other suggestions,
    Vito

Well I don't know what extra one has installed, but I can confirm that the SVN trunk of last Friday (can't remember what concrete number it was) worked flawlessly for me. OS X Lion + Xcode 4.2.x (the one you get from App Store for free) was enough. I just did a ./configure macosx64; make; and voila it worked.
